One sporting organisation, the Twin City Archers has lost its field course which took 10 years to construct.

Club president Peter Bennett said members were still dampening smouldering earth after the fire cut through the area about 4pm yesterday.

"One of our guys was down there and saw the fire coming and moved all the machinery into the middle of our target range because the grass was short," Mr Bennett said.

"He tried to get out but the fire had already cut the road so he went back in there and just hosed down around the clubrooms.

"He got out in the end but probably saved the clubrooms."

Laurie Jeremiah from the Traralgon Incident Control Centre said the fire started at the Princes Freeway interchange at Hernes Oak near Moe last Friday.

Sunday's northwesterly winds fanned the fire along the freeway and railway line easements to the Morwell River.

The southwesterly change took the fire into the Morwell township but today's cooler conditions have assisted the fire fighting effort.

"Fire behaviour right now is benign but by the middle of the afternoon it will be actively burning in a number of places," Mr Jeremiah said.

"They are still burning, they will do things this afternoon but not to the degree of yesterday."

The southwesterly change pushed the fire from the edge of Morwell through a pine plantation and into Australian Paper's Maryvale Mill.

Large log piles on the site are on fire and there has also been damage to part of the plant forcing its shutdown.

"The operation is currently not up and running. We expect it to progressively come back on stream over the course of the next 24-48 hours," Maryvale Mill spokesman Mark Nelson said.

Fire is also burning in a coal mine on the southern side of Morwell.

The fire spotted from the Princes Freeway and is burning in the disused northern section of the Morwell Mine.

The fire has cut power to the mine leaving dredgers and conveyor belts inoperable.

"Fortunately it is some considerable distance from the operating face of the mine," GDF Suez spokesman Trevor Rowe said.

"We've lost power to the mine as a result of SP Ausnet powerlines being damaged by the fires.

"There's been no coal dug overnight and we've been conserving coal with the (Hazelwood) power station overnight but even with running it at reduced levels we're now down to only two units operating out of the eight units."

Mr Rowe said the reduced generation was not expected to affect power supplies to consumers.

Relief centres for evacuees were still operating at Traralgon and Moe today.

More than 430 people registered at the Moe centre and 229 at Traralgon.

Almost 60 people stayed overnight at the Traralgon centre and 200 at Moe. People were also accommodated at Federation University in Churchill and at Centenary House in Traralgon.

"A lot were people coming through because the highway was cut off," Latrobe City Mayor Sharon Gibson said.

"We've had the Lions Club down there cooking breakfast for them so we've given them as much support as we could."
